ある。[Detailed Description of the Invention] The present invention provides a concave groove with a large number of grooves arranged adjacent to each other in the circumferential direction of the tire so that the bottom of the groove is rectangular.
In addition to extending in a direction perpendicular to the circumferential direction of the tire, each of the above-mentioned grooves is divided and separated by a vertical web and a circumferential web. The present invention relates to a tread structure for an automobile pneumatic tire, particularly a spare tire, having a tie type.
この7重のトレッド構造は乗用車の予備タイヤ用に既に
提案されていて、予備、タイヤが特別の走行音を出しな
がら路上を転動するようにし目一つ予備タイヤ重数の軽
減化を計ってい乙。This seven-layer tread structure has already been proposed for spare tires for passenger cars, and is designed to allow the spare tires to roll on the road while producing special running sounds, thereby reducing the weight of the spare tires. Otsu.
−に記公知の予備タイヤにより従来の通常タイヤに比べ
て大きい走行音が得られるけれども、乗用車のドライバ
が出来るだけ帰り途中に取・換える必要のちる予備タイ
ヤを取付けていることを同ドライバに想起させる程度の
走行音が同予備タイヤから生じないことが判明した。Remind the driver that although the known spare tires mentioned above produce a louder running noise than conventional regular tires, drivers of passenger cars often install spare tires that need to be replaced on the way home if possible. It was found that the spare tires did not produce the kind of running noise that would cause such noise.
従って本発明の目的はドライブ中の走行そう音を改善す
るタイヤ・トレッド構造を記述することである。It is therefore an object of the present invention to describe a tire tread structure that improves road noise during driving.
